A New Document on Smallpox Vaccination.

Modern medicine owes much to the invaluable heritage of the practices of past generations and their achievements that have now become medical rules. In the case of vaccination, there is evidence that the nomads of Baluchistan (Southeast Iran) demonstrated natural immunization against cowpox, a practice that was later introduced to the medical community by Edward Jenner. Although the discoveries of scientists cannot be ignored, they are certainly based on the traditional and indigenous experiences that have been transferred from generation to generation until reaching us.
